VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 389,512, datedSeptember 11, 1888.

Application tiled April 1S, 18S8. Serial No. 271,098, (No model.)

To all whom it may concern.-

Be it known that I, MILO P. HOLMES, a citizen of the United States,residing in the city and county of San Francisco,and State of Califorma,have invented certain new and useful Improvements in Triple-Spring Gearfor Wagons; and I do hereby declare that the followlng 1s a full, clear,and exact description of my said invention, reference being had todrawings that accompany and form part of this specification.

' My invention relates to improvements in springfgear for wagons; and itconsists in the combination of side springs and end springs,as'hereinafter fully described, by which the prlnciple of what is knownas the triplesprlng gear is applied and adapted to business-wagons andlike vehicles for carrying merchandise.

These improvements have for their object to secure suitable strength andstability, an equal distribution of the weight of the load, lanextension of the wagon-body beyond the springs, and all the advantagesof the triplespring gear as well.

The nature of these improvements and the manner in which I proceed toconstruct, app ly, and carry out the same to secure the deslred ends andobjects are explained and set fortlr in the following description, inwhich the accompanying drawings are referred to by letters and figures.

Figure l is an end View in elevation taken from the back of thespringgear, and showing the wagon-body set on it. Fig. 2 is aside viewof the same, showing about One-half of the length. Fig. 3 is aperspective view ofthe same without the body.

Similar letters of reference indicate like parts in all the figures ofthe drawings.

A is the hind axle, and B the wagon-body.

C C are the side springs, and CX is the `center spring, that is placedmidway along the space between thesidesprings, and, like them, isconnected to the front and hind axles. The connections are the same atboth axles, except that the side springs at their front ends areattached to the bolster instead of directly to the axle, and the centerspring is suitably connected to the axle by a swivel to allow for themovements ofthe front'axle in turning on its center. This isA the Inodeof connecting the springs in the triple-spring gear at the pres enttime.v The springs C are attached by shackles d d in the usual way abovethe axle, but the' center spring is attached beneath the axle at themiddle. The center spring being somewhat lower than the side springs forthis reason, it is attached to the bottom of the wagon-body by theC-springs E E, that are fastened by clips e c at their lower ends and byboltsff to the body. The side springs are secured to the blocks BX underthe sides of the body in the usual way.

G are the end springs. These are set parallel with and above the axlesto receive and give support to the wagon-body at the ends, and they areattached at the ends to the top of the axle by means of the studs hh,that are secured in place by clips hX and by the eyes on the ends of thesprings.

GrX GX are curved arms that are fastened by clips t' i upon the top ofthe spring at the middle, and are curved upwardly and outwardly to takethe body. 'Iheir outer ends are thus thrown beyond the line of the axleand the end spring, so that the support to the bodyis brought at bothends of the gear outside of the axles.

By setting end springs in this way I secure two results-rst, anextension of the body at the ends, thereby increasing its carryingcapacity, and, secondly, a distribution of the weight upon both sides ofthe axles, thereby obtaining greater stability and preventing the axlesfrom canting,7 as they are liable to do Where the ordinary tri plespringgear is subjected to a heavy load. As thus arranged and combined thebody and its load is borneevenly upon all the springs and the Weight isequally distributed over the gear. In this Way a triple-spring gear canbe made to bear aheavy load, and can be therefore employed to advan tagein building business-wagons and other comparatively light vehicles forcarrying merchandise, to which such spring-gear is otherwise not welladapted by reason ot' its lightness, the liability of the axles to cantunder a heavy load, and the impossibility of extending the body outsidethe axles.

It will be evident that double springs could be used in place ofthesingle springs G,where greater stiffness at the ends of the gear wouldbe an advantage; and in such case the springs ICO would be fastened uponthe axle at the rear of the gear and on the bolster at the front byclips in the usual way. The arms GX, being secured on the springs andhaving suitable curvature upwardly and outwardly,will throw the weightof the body and its load to a sutable point outside the line of theaxle.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In avehiele-spring, the eonibil1atiou,\vith the longitudinal springs,of the transverse end springs having curved arms on the top thereofwhich are curved upwardly and ontwardly, their ends being attached tothe vehiclebody beyond the axles, substantially as described.

2. The combination, with the side springs, C C, of the end springs, G,arranged parallel with and above the axles, and the curved arms Gf G,fastened on the top of springs G and curved upwardly and outwardly, soas to support the vehicle-body at points beyond the axles, substantiallyas described.

3. The combination, with the side springs, C C, and center spring, C,attached to the vehicle-body by C-springs E E, tbe end springs, G,arranged parallel with and upon the axles. and the curved arms GX,fastened to springs G and curved upwardly and outwardly, so as tosupport the vehicle-body at points beyond the axle, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand andseal.
